Strokkur Geyser at Geysir

Iceland

Iceland is known as the Land of Fire and Ice because it's populated by glaciers and volcanoes in just about equal measure. The land here is alive, which you can see in this photo from Haukadalur geothermal valley.
In this photo, the Strokkur geyser is just beginning to erupt, which it does regularly roughly every 4-7 minutes.
Have you ever seen a geyser erupt in person?
